Doubt about a question
Hi,
Recently, Oracle University posted on his Facebook's wall a question:
You created a new user on the database by executing the following command:
SQL> CREATE USER user01 IDENTIFIED BY user01
DEFAULT TABLESPACE users
TEMPORARY TABLESPACE temp;
Then you granted the following privileges to user01
by executing the following command:
SQL> GRANT CREATE SESSION, CREATE TABLE TO user01;
Which statement is true in this scenario?
1. The user can connect to the database
2. The user will be able to create a table
3. The user will be able to query tables only
4. The user will not be able to create a table if
DEFAULT_PERMANENT_TABLESPACE is not setAfter many comments with possible correct answers (most of people said 1 and 2), Oracle University replied: Many conflicting opinions here - the correct answer is #4 - The user will not be able to create a table if DEFAULT_PERMANENT_TABLESPACE is not set.
My question is.. WHY 4? Why not 1? Because the user can connect to the database. Also 2 is correct! It can create a table, but having no quota assigned, he cannot insert data into the table. So why 1 and 2 are not correct?
go to test it (oracle version 11.2.0.1 on windows):
option 1:
SQL> CREATE USER user01 IDENTIFIED BY user01
2 DEFAULT TABLESPACE users
3 TEMPORARY TABLESPACE temp;
Usuario creado.
SQL> conn user01/user01
ERROR:
ORA-01045: user USER01 lacks CREATE SESSION privilege; logon denied
Advertencia: íYa no estß conectado a ORACLE!no rol connect, the user can't connect to the database.
Option 2
2. The user will be able to create a tablethe user can't connect to the database so he can't create anything.
If he has the rol connect-:
SQL> conn / as sysdba
Conectado.
SQL> grant connect to user01;
Concesi¾n terminada correctamente.
SQL> conn user01/user01
Conectado.
SQL> create table test(id number, name varchar2(25));
create table test(id number, name varchar2(25))
ERROR en lÝnea 1:
ORA-01031: privilegios insuficientesStill not enough privileges.
Option 3
3. The user will be able to query tables onlythe user must have "grant select table XXXXX" , to query all tables you must grant select on all tables, something similar like this:
FOR x IN (SELECT * FROM user_tables)
LOOP
EXECUTE IMMEDIATE 'GRANT SELECT ON ' || x.table_name || ' TO <<someone>>';
END LOOP;
*remember that with this user creation query, the user can't connect, so he also can't select anything.

Many doubts about your questionable "change for better" new conditions
I Am an early adopter of Revel and a satisfied customer. I upgrade my account some months every year if I have done more than 50 pics I want to save on Revel. When downgrading my pics remain on Revel. Fantastic!
With the new terms I would have to pay for a permanent upgrade as my account raises the 2Gb free that you are offering.
this not a change for better as you say. Not at all.
As an early adopter will I keep the billing rigths and conditions that I signed up when I subscribed the service? I wait for a clear answer as I am thinking about deleting my account.
Your change sound like a trick... now that I have spend lots of time upgrading many Gb you change the conditions. Not wise at all. and the worst is that we don't know what are you planning for the future....Darderes-
The new model will not change how the premium accounts work, but all free users will be using the new model once the changes take place. We realize this may benefit some users and not others and apologize if it causes you any inconvenience.

Doubt about a null value assigned to a String variable
Hi,
I have a doubt about a behavior when assigning a null value to a string variable and then seeing the output, the code is the next one:
public static void main(String[] args) {
String total = null;
System.out.println(total);
total = total+"one";
System.out.println(total);
}the doubt comes when i see the output, the output i get is this:
null
nulloneA variable with null value means it does not contains a reference to an object in memory, so the question is why the null is printed when i concatenate the total variable which has a null value with the string "one".
Is the null value converted to string ??
Please clarify
Regards and thanks!
Carlosnull is a keyword to inform compiler that the reference contain nothingNo. 'null' is not a keyword, it is a literal. Beyond that the compiler doesn't care. It has a runtime value as well.
total contains null value means it does not have memory,No, it means it refers to nothing, as opposed to referring to an object.
for representation purpose it contain "null"No. println(String) has special behaviour if the argument is null. This is documented and has already been described above. Your handwaving about 'for representation purpose' is meaningless. The compiler and the JVM don't know the purpose of the code.
e.g. this keyword shows a hash value instead of memory addressNo it doesn't: it depends entirely on the actual class of the object referred to by 'this', and specifically what its toString() method does.
similarly "total" maps null as a literal.Completely meaningless. "total" doesn't 'map' anything, it is just a literal. The behaviour you describe is a property of the string concatenation operator, not of string literals.
I hope you can understand this.Nobody could understand it. It is compete nonsense. The correct answer has already been given. Please read the thread before you contribute. -
Doubts about BP number in SRM and SUS
Hello everyone,
I have some doubts about the BP number, especially for Vendors.
I am working with the implementation of SRM 5.0 with SUS in an extended classic scenario. We will use one server for SRM and other for SUS. We will use the self registration for vendor (in SUS). My questions are:
- Can I have the same BP number in SRM and SUS?? Or is it going to be different??
- When a vendor accesses at the site to make a self registration in SUS, the information is sent to SRM as prospect (by XI) and there the prospect is changed as vendor? After that, is it necessary to send something from SRM to SUS again? (to change the prospect to vendor)
- When is it necessary to replicate vendors from SRM to SUS??
Thanks
IváDear Ivan,
Here is answer to all your questions. Follow these steps for ROS configuration:
Pls note:
1. No need to have seperate clients for ROS and SUS. Create two clients for EBP and (SUS+ROS).
2. No need of XI to transfer new registered vendor from ROS to EBP
Steps to configure scenario:
1. Make entries in SPRO --> "Define backend system" on both clients.
You will ahev specify logical systems of both the clients (ROS as well as EBP)
2. Create RFCs on both clients to communicate with each other
3. In ROS client create Service User for supplier registration service with roles:
SAP_EC_BBP_CREATEUSER
SAP_EC_BBP_CREATEVENDOR
Grant u201CS_A.SCONu201D profile to the user.
4. Maintain service user in u201CLogon Datau201D tab of service : ros_self_reg in ROS client
5. Create Purchasing and vendor Organizational Structure in EBP client and maintain necessary
attributes. create vendor org structure in ROS client
6. Create your ROS registration questionnaires and assign to product categories- in ROS client
7. To transfer suppliers from registration system to EBP/Bidding system, Supplier pre-screening has to be
defined as supplier directory in SRM server - EBP client.
Maintain your prescreen catalog in IMG --> Supplier Relationship Management u2192 SRM Server u2192
Master Data u2192 Define External Web Services (Catalogs, Vendor Lists etc.)
8. Maintain this catalog Id in purchasing org structure under attribure "CAT" - in EBP client
9. Modify purchaser role in EBP client:
Open node for u201CROS_PRESCREENu201D and maintain parameter "sap-client" and ROS client number
10.Maintain organizational data in make settings for business partner
Supplier Relationship Management -> Supplier Self-Services -> Master Data -> Make Settings for the Business Partners. This information is actually getting getting stored in table BBP_MARKETP_INFO.
11. Using manage Business partner node with purchasers login (BBPMAININT), newly registsred vendors are pulled from Pre-screen catalog and BP is created in EBP client. If you you have SUS scenario, ensure to maintain "portal vendor" role here.
I hope this clarifies all your doubts.
Pls reward points for helpful answers

Hello
I have a doubt about string.intern() method.
The document says
When the intern method is invoked, if the pool already contains a string equal to this String object as determined by the String.equals(Object) method, then the string from the pool is returned.
So what is the point of using this intern() method with == or != operators if it aleady calling to equals method internally?
eg:
if (studentObject.getName().intern() == "Student Name") {}cannot be better than
if (studentObject.getName().equals("Student Name")) {}Can someone please explain?Easy dude.
>
Why do you need to optimize it?>
Because i want to.
I would avoid the whole stupid 100 line if-else by doing a Map of type->object and then just clone() the object. But maybe that might not be suitable or "fast enough" for you.I cannot do above because object have it's own behaviors varying at run time
eg - class One has setOne method and class hundred has setHundred method
. Even if i use a map and clone it again i have to use above comparison for setting those behaviours.
Explain your actual problem you're trying to solve, with actual cases. What are these "one" and "Hundred" classes really? Or is your project so top secret that you can't tell us?It is not secret but big. And I need to make the question understandable. If I post the whole code no one will looking at it.
Now you asking so please have a look.
still I have cleaned up many.
My initial question was how to bit speed up the comparison? And can't i use intern() Because here if I got plenty of rectangles(it is the last) performace sucks.

Doubt about Component binding....
I have a doubt about component binding because I am also using component binding in my application, in my application each page has more than 20 components and each page is session scope, at one point I am getting message like perm space(this is because of lack of memory, actually I have 4gb ram). So my is
"does the jsf creates new object for every reload, because of that my jvm filling with all the objects?".
Another question is "what is the difference between value binding and component bindings?, and drawbacks of each other" please tell me the differences between them up to the very low level(up to memory usage for each approach).

So my is
"does the jsf creates new object for every reload, because of that my jvm filling with all the objects?".This is regardless of the component binding. JSF creates a component tree and stores it in the session. With component binding you can link between the backing bean and the component without the need for UIViewRoot#findComponent().
Think your problem lies somewhere else. Use a profiler.
Another question is "what is the difference between value binding and component bindings?, and drawbacks of each other" please tell me the differences between them up to the very low level(up to memory usage for each approach).With the component binding you can get hold of the whole component from the tree in the backing bean. Useful if you want to do a bit more than only holding the component's value, with which you usually do with the value binding. -
Doubts about performance:
Hi:
In my work we have performance problems with the database (Oracle 9i v. 2), we have said that the TOAD consumes a lot of resources.
I know how to affect the performance of the database using a tool such as the toad.. ?
It is true that the use of inner join and left join instead of = and (+) is better?
ThanksThis is too broad a question.
Toad can fire random sql.
sql*plus can fire random sql.
Why would Toad be the problem?
You would need to gather statspack data to demonstrate this.
Sybrand,
Agreed on it and its a relevant point.But I guess he is not worried about the db performance.Anyways lets see what OP says.
Inner join and left join will always use CBO (Cost Based Optimizer) instead of RBO.
I am not sure that I have read that anywhere. They came into Oracle in 9i where optimizer mode was choose as the default one. Just by the syntax, oracle would push them to use CBO as the default one,I am not sure about this. Even if we are having + symbol and have the stats,Oracle wold go for CBO right?Can you please point me to some where in the docs where it is mentioned that using this keywords,Oracle would use only CBO?

Hi folks!!
I have a few doubts about the select statements, it may be a silly things but its useful for me.
what is difference between below statment.
1)SELECT * FROM TABLE.
2)SELECT SINGLE * FROM TABLE
3)SELECT SINGLE FROM TABLE.
Hope i will get answer,thanks in advance.
Regards
Richie..Hi,
try this and if possible use sap help.i mean place the cursor on select and press F1.
Types of select statements:
1. select * from ztxlfa1 into table it.
This is simple select statement to fetch all the data of db table into internal table it.
2. select * from ztxlfa1 into table it where lifnr between 'V2' and 'V5'.
Thisis using where condition between v2 and v5.
4. select * from ztxlfa1 where land1 = 'DE'. "row goes into default table work Area
5. select lifnr land1 from ztxlfa1
into corresponding fields of it "notice 'table' is omitted
where land1 = 'DE'.
append it.
endselect.
Now data will go into work area. and then u will add it to internal table by
append statement.
6. Table 13.2 contains a list of the various forms of select as it is used with internal tables and their relative efficiency. They are in descending order of most-to-least efficient.
Table 13.2 Various Forms of SELECT when Filling an Internal Table
Statement(s) Writes To
select into table it Body
select into corresponding fields of table it Body

INNER JOIN T001 ON VBRKBUKRS = T001BUKRS
WHERE VBELN IN DOCNUM AND VBRK~FKSTO = ''
AND VBRK~FKDAT in date.
Select statement using inner joins for vbrk and t001 and tvkot table for this case based on the conditions
8. SELECT T001W~NAME1 INTO TABLE IT1_T001W
FROM T001W INNER JOIN EKPO ON T001WWERKS = EKPOWERKS
WHERE EKPO~EBELN = PURORD.
here selecting a single field into table it1_t001winner join on ekpo.
9. SELECT BUKRS LIFNR EBELN FROM EKKO INTO CORRESPONDING FIELDS OF IT_EKKO WHERE EBELN IN P_O_NO.
ENDSELECT.
SELECT BUTXT FROM T001 INTO IT_T001 FOR ALL ENTRIES IN IT_EKKO WHERE BUKRS = IT_EKKO-BUKRS.
ENDSELECT.
APPEND IT_T001.
here I am using for all entries statement with select statement. Both joins and for all entries used to fetch the data on condition but for all entries is the best one.
10. SELECT AVBELN BVTEXT AFKDAT CBUTXT ANETWR AWAERK INTO TABLE ITAB

The page that you posted from has instructions for how to reset them i.e. if you have a rescue email address (which is not the same thing as an alternate email address) set up on your account then steps 1 to 5 half-way down that page should give you a reset link.
If you don't have a rescue email address (you won't be able to add one until you can answer your questions) then you will need to contact iTunes Support / Apple in your country to get the questions reset (these are user-to-user forums).
Contacting Apple about account security : http://support.apple.com/kb/HT5699
When they've been reset (and if you don't already have a rescue email address) you can then use the steps half-way down the HT5312 page that you posted from to add a rescue email address for potential future use -
Doubt about Bulk Collect with LIMIT

could crash redo log ?
using 9.2.08muttleychess wrote:
If my table Servers have 3 000 000 records , when is done commit ? Commit point has nothing to do with how many rows you process. It is purely business driven. Your code implements some business transaction, right? So if you commit before whole trancaction (from business standpoint) is complete other sessions will already see changes that are (from business standpoint) incomplete. Also, what if rest of trancaction (from business standpoint) fails?

I have some doubts about the possible uses of OBIEE. It happens that using OBIEE sometimes users demand report of an "analytical" type, that is aggregated analysis through OBIEE’s Answers, selecting data from dimension tables and measures from fact tables. That’s the ordinary purpose of business intelligence tools!!!
Some other times though, users demand to perform through Answers analyses of an "operating" type, that is simple extractions of some fields belonging to dimension tables, linked between each other through joins, (hence without querying fact tables): that happens because some of the tables brought in the datawarehouse are not directly linked to any fact table. In this way users want to use Answers to visualize data even for this kind of extractions (or operating reports).
Is this a correct use of the tool or is it just a “twisted” way of using it, always leading eventually to incorrect extractions? If that’s the case, is it possible to use instead BI Publisher, extracting the dataset through the "Sql Query" mode in a visual manner? The problem of the latter solution, in my case, relies in the fact that users are not enough skilled from the technical point of view: they would prefer to use Answers for every extraction, belonging both to the first type (aggregations) and the second one (extractions), that I just described. Can you suggest a methodology to clarify this situation?Hi,
I understand your point... But I think OBIEE doesn't allow having dimension "on their own", they must be joined to a fact table somehow. This way, when you do a query in answers using fields of two dimension tables a fact table should be always involved. When dimensions are conformed, several fact tables may be used, and OBIEE uses the "best" one in terms of performance. However, there are some tricks that you can do to make sure a particular fact table is used, like using the "implicit fact column" in the presentation layer.
So back to your point, using OBIEE for "operational" reporting as you call it is a valid option in my experience, but you have to make sure that the underlaying star schema supports the logic that your end users expect when they use just dimension fields.

Doubts about use of REPORTS_SERVERMAP with Forms11g HA
Hi,
I'm configuring a Linux 64bits Forms/Reports 11g HA environment, the point is that i have two nodes, each one with its Forms and Reports servers, let's say FormsA and ReportsA for the first node and FormsB and ReportsB for the seconde node.
i want FormsA to be able to call reports from ReportsB and FormsB to be able to call reports from ReportsA.
I've been reading about REPORT_SERVERMAP
http://docs.oracle.com/cd/E12839_01/bi.1111/b32121/pbr_conf003.htm#autoId5
But i have some doubts about its use:
1. I will not use a shared cluster file system or any way of cache solution, i will only have my rdf files on each node, and i'm wondering if just by configuring this parameter i will be able to get the effect mentioned above ??
2. The link provided says "Using RUN_REPORT_OBJECT. If the call specifies a Reports Server cluster name instead of a Reports Server name, the REPORTS_SERVERMAP environment variable must be set in the Oracle Forms Services default.env file"
In fact i'm using RUN_REPORT_OBJECT but
what is the Reports Server cluster name ?? and where do i find that name ??
3. Is this configuration well defined:
REPORTS_SERVERMAP=clusterReports:ReportsA;clusterReports:ReportsB
4. At forms applications when using RUN_REPORT_OBJECT, can i assume that the report server name will be the cluster name specified at the REPORTS_SERVERMAP ??
5. Which files should i modify rwservlet.properties or default.env ??
Hope you can help me :)
Regards
CarlosHi,
1. I will not use a shared cluster file system or any way of cache solution, i will only have my rdf files on each node, and i'm wondering if just by configuring this parameter i will be able to get the effect mentioned above ??
--> In such case what could go wrong is
Suppose Run_report_object executed jobs successfully to ReportsA
But web.show_document command for getjobid failed ( as ReportsA went down by this time)
--> You will not get the output shown ( though job was successful)
If shared cache was enabled, then Even if ReportsA is down, other cluster member ( say ReportsB)
will respond back to web.show_document.
Point 2,
--> Under HA is it highly recommended to use web.show_document ( a servlet call) to execute reports. This is to help use all HA features at the HTTP , Webcache or load balancer level.
However if there is migrated code or Run_report_object is must, then the recommendations as you see in the pointed document is must.
REPORTS_SERVERMAP setting needs to be configured in rwservlet.properties file and also in default.env Forms configuration file to map the Reports Server cluster name to the Reports Server running on the mid-tier where the Load Balancer forwarded the report request.
For example FormsA, ReportsA, cluster name say rep_cluster
default.env file
REPORTS_SERVERMAP=rep_cluster:ReportsA
Where "rep_cluster" is the Reports Server cluster name and "ReportsA" is the name of the Reports Server running on the same machine as FormsA
rwservlet.properties file
<reports_servermap>rep_cluster:ReportsA</reports_servermap>
At default.env this is not a valid entry
REPORTS_SERVERMAP=clusterReports:ReportsA;clusterReports:ReportsB
what is the Reports Server cluster name ?? and where do i find that name ??
--> This is created via EM on the report server side.
Would recommend to refer following documents at the myoracle support repository
How to Setup Reports HA (High Availability - Clusters) in Reports 11g [ID 853436.1]

Doubt about proxies implementation
hi experts i have small doubt about proxies implementation
1. if we r implementing client proxies, it means sap r/3(proxy)->>xi->>>file
system.here where we have to execute the SPROXY transaction. in sap r/3 or
in the xi server.and the next thing is where we have to write the report program
to trigger the interface.in sap r/3 or in the xi server.
2. if we r implementing server proxies, it means File->>xi->>>sap r/3
(proxy).here where we have to execute the SPROXY transaction. in sap r/3 or
in the xi server.
please clear me
Regards
giriSreeram,
The Integration Server and the client on which you generate the proxies should not be the same. If they are different then yes, you can use another client in your XI box itself to generate proxies and trigger the call to XI.
If you see this blog by Ravi ( incidentally he is my boss as well ) this is exactly what we have done as well.
/people/ravikumar.allampallam/blog/2005/03/14/abap-proxies-in-xiclient-proxy
When you say XI, you mean the Client on which the Integration Server is running! XI is basically a R3 instance with more functionality and its own Integration Engine.

Doubt about unicode conversion
Dear Friends,
I have a doubt about the unicode conversion. I have read (one server strategy) that I have to do export (R3load), delete the ECC 6.0 non-unicode, install an unicode database and then import with R3load. My doubt is about the deletion of ECC 6.0 non unicode. Why? can I convert to unicode only with an export (R3load) and subsequent import (R3load) without any deletion?. Obviously I must to change the SAP kernel with a unicode one. Is it correct?
Cheersyou can not convert a SAP System to unicode by just exchanging the executables from non unicode to unicode ones.
a non unicode SAP Oracle database is typically running with a database codepage WE8DEC or US7ASCII (well this one is out of support).
so every string stored in the database is stored using this codepages or SAP-Internal codepages.
When converting to unicode you have to convert also the contents of the database to unicode. As unicode implementation starts at a time where Oracle did not support mixed codepage databases (one tablespace codepage WE8DEC the other one UTF8) inplace conversions are not possible. To keep things simpler, we still do not support mixed codepage databases.
Therefore you have to export the contents of your database and import it to a newly created database with a different codepage if you want to migrate to unicode.

Hi everyone!
I have a doubt about applying patch.
I just applied this patch (using GUI):
Oracle® Database Patch Set Notes
*10g Release 2 (10.2.0.4) Patch Set 3 for Microsoft Windows (32-Bit)*
Initially, there was an error stating that some other process is accessing one particular dll.
I ignored it.
I rerun the patch installation thinking that I need to get that dll as well.
It gave a list of what has been installed and what can be installed.
So, I selected all the remainders and installed.
It was successful. Now, would it have ignored that dll or installed it?
Please advice.
Thanks in advance.

Edited by: user645399 on Nov 26, 2010 10:24 AMEvenif you've stopped all the windows services, sometimes some DLLs remains utilized. What I do is, make all the oracle related services manual and then restart the server.
You can't ignore any dll related errors. If a dll is in use, oracle patching process will not replace that with a newer version of dll. I'll strongly recommend the use of ' Microsoft Process Monitor' utility to monitor, what is running on my server.
